VistasAngular table row not spanning table as expected?
I have a very simple Angular app that creates a table of items, say "products".
I have a component called "Products" and a sub-component (if that is the terminology) called product-item.
My problem is with the column span of rows from the sub-component. As a test I did the following to show my issue:
In the "Products" component, I have the following HTML:
<table [ngClass]="{'blueTable':true}">
<thead>
<tr>
<th>head1</th>
<th>head2</th>
<th>head3</th>
</tr>
</thead>
<tbody>
<tr>
<td>test c1</td>
<td>test c2</td>
<td>test c3</td>
</tr>
<!-- <ng-container *ngFor="let docketItem of docketList"> -->
<ng-container *ngFor="let number of [0,1,2]">
<app-product-item></app-product-item>
</ng-container>
</tbody>
<tfoot>
<tr>
<td>foot 1</td><td>foot 2</td><td>foot 3</td>
</tr>
</tfoot>
</table>
In the "product-item" component, I have the following HTML:
<tr>
<td>cA</td>
<td>cB</td>
<td>cC</td>
</tr>
This is the output:
My goal is that each product-item row is a new row in the table. What am I not understanding?

A tr element must be a direct child of table element or of thead/tbody/tfoot
If you will check in your DOM, you have inside the tbody an app-product-item element that contains the tr
I assume you tried to fix by using ng-container and that's why you didn't do simply:
<app-product-item *ngFor="let number of [0,1,2]"></app-product-item>
But still the tr is inside the app-product-item
You should use attribute selector, and then in the "Products" component, have the following:
<tbody>
<tr app-product-item *ngFor="let number of [0,1,2]"></tr>
</tbody>
In the "product-item" component, get rid of the tr
And in the "product-item" ts file, change the selector to:
@Component({
selector: '[app-product-item]',
...
